The fishing rod website shows that the guide ring of this fishing rod has both a square guide ring and a round guide ring.

1. Circular guide ring: When the circular guide ring is stressed, each part of the circular guide ring is relatively evenly stressed and is not easily damaged. The strength and wear resistance of round guide rings are not as good as square guide rings.

2. Square guide ring: Square guide ring, also known as FUJ guide ring, is made in Japan. This kind of guide ring is usually used on mid-to-high-end rock fishing rods. When the square guide ring is stressed, it mainly bears shear force, so it is not easily damaged. The strength and wear resistance of square guide rings are higher than that of round guide rings.
